Toall wimmelt may concern.; 1

Be it known that I, AUGUST STEINMANn, a citizen ofthe'UnitedrStates, anda resident of the city of Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in a ShockAbsorber; vand I hereby declare that the following 'is a full, clear,and exact description of the same, reference being had to theaccompanying drawings, and to the numerals of reference marked thereon,which form a part of this Specification.

This invention relates to a shock absorber for automobiles and consistsof a simple structure that can readily be applied to cermerals refer tosimilar parts in the different Figure l is an elevational vew'of therear axle casing of a Ford car showing my shock absorber appliedthereto.

Figure 2 is, an enlarged elevational view -of the `shock :absorber witha portion of the vehicle spring attached thereto. i

o VFigure 3 is a frontv elevational view of the shock absorber. f

Figure 4 is an enlarged sectional view vtaken substantially uponV theline of Figure 2.

In referring now to the drawings, 'there is illustrated a verticalstandard l having a bolt hole at its lower end which is adaptedtoreceive ,a bolt 1a extending through `the usual hole in the side oftheaxle casing in which the spring suspension T-bolt is normallysecured. The upper end of thestandard l' is provided witha flat inwardlydirected apertured lug 2.- A pair of parallel metal strips 3 are pivotedat their outer Ypivot bolt 2?, the inner endsof said strips ends uponopposite' sides of the lug `EZby a4 having integrar' branlette Hgtenaigte right angles thereto.

A pairof' parallel bars. 5.A are pivotedfat `one end to the'lowerportion ofthe standardl by means of a commonpivot 6. TheV Y other endsof these bars are ,connected by a bolt 7 having a pair of spacingsleeves 8. A flat bar 9 is pivoted between the sleeves S upon the bolt 7and extends betweenvthe parallel Hat bars 3.V The free end ofthe bar9.is provided with oppositely'j'extending lugs "10. A coil springllsurrounds the bars 3 and 9 withl its ends respectively abutting theabutments 4 and lugs 10. Besides its ordinary function of absorbing the-shock the spring ll also holds the bars 3 and' 9 in parallel andtelescopic relation.

lA U shaped clip 12` is welded or secured in some appropriate mannervover thefbars e 5; the arms of the Vclip-being attached to the bars andthe connectingweb ofthe arms .A bolt aperture is made centrally oftheweb,

and a T-shaped bolt 13 is :secured` by a nut,k

bridging the space between thebars.

and depends therefromfand the stirrup 14 vvofthe vehicle springs isattached thereto. -This T-shaped bolt V13 visexactly like the one now`invuse upon Ford cars, so that Vin applying the shock absorber, theT-shaped bolt yon the car may be utilized..v

vShock absorbers of thetype just described may be quickly and easilyapplied to'automobiles and vehicles. WhenV it is desired to applythesame to a Ford car or the like, it isonly necessary to remove the twoT-shaped bolts that connect the spring to theaxle casing. My shockabsorbers may then be*y attached by means of bolts 1?L extending throughthe holes'left vacant by the T-shaped bolts. The removed Tfshaped boltson the ends of the' spring mayA then be secured to the U-shaped clips12as before explained whereby the vehicle springs become suspended uponthe shock absorbers as shown in Figure l. V i

In operation any Jolt orV jars'l ofthe vehicle lwill swing the pivotpoints l'defined by the bolt 7 downwardly. This actionv will increasethedistance between the pivots 2a l and7 andcompress the springs 11` forabsorbing'the shock; the expansible and conioo tractable feature of thetelescopicv fbars "3 and 9 permitting VVsuch action.

From the foregoing, it will be apparent sorher has been provided thatmay be readily applied 4without any Change and Valtera-` tions toexisting automobiles,v I am aware that many changes may be made, andvnumerous details of construction Ymaybe varied through a wide rangewithout departing from the principles of 'this invention, and Itherefore do not purpose V,limiting the patent granted hereon, otherwisethan necessitatedvby the prior art.

` Iolaim: Y

In a shock absorberfa vertical standard,

I scribed -lny naine.-

an inclined har pivoted` at its lower end Y to the lower portion of saidstandard, horizontally disposed bars lconnected respective` ly with theupper ends'of said lstandard and inclined bar and in telescopic relationas to each other, and a spring encircling said latter .hars and adaptedto exert a compression resistance against vdownward inoveinent of thevehiole'body. 1 s

In testimony whereof I have hereunto sub- AUGUST STEINMANN.
